REGISTERING ATTACHMENT FOR FAUCETS.

SPECIFICATION forming part of Letters Patent No. 327,663, dated October 6, 1885.

Application filed July 9, 1885. Serial No. 171,061. (No model.)

To all whom it may concern.-

Be it known that we, DAVID W. DAVIS and WILLIAM G. LATIMER, of Detroit, in the county of WVayne and State of Michigan, have invented new and useful Improvements in Registering Attachments to Faucets; and we do hereby declare that the following is a full,

I clear, and exact description thereof, reference being bad to the accompanying drawings, which form a part of this specification.

This invention relates to a new and useful improvement in automatic registering attachments for faucets, and the improvement is especially designed for use in connection with the dispensing of liquid refreshmentssuch as beerto keep an exact register of the number of glasses or drinks drawn through the faucet.

The object of the device is mainly to keep a check on bar-keepers and other employs as to the number of glasses or drinks sold, as no glass can be filled without its being automatically registered.

The invention consists, first, in the peculiar arrangement and combination of a valve with means for opening it by contact and pressure with the glass to be filled; second, in the combination of said valve with the registering device; third, in certain features of construction which prevent fraudulent tampering with the device; fourth, in the peculiar construction and arrangement of the parts which give the device the nature of an attachment to faucets.

In the drawings which accompany this specification, Figure 1 is a perspective view of the device attached to a common beer-faucet,some parts being partially broken away. Fig. 2 is a vertical central section, showing the position of the parts in the act of filling a glass.

A is a beer-faucet of the ordinary kind, abeing the discharge end, and b the plug.

B is an inverted conical or bell-shaped cup, with the wall or sides preferably of glass.

0 is a tube secured to and passing centrally through the bottom of the cup, and having a flange, c, projecting upwardly from the bottom of the cup. This tube is of suitable size and form to allow the cup to be slipped far enough onto the discharge end of the faucet and be secured thereon by set-screws d, or otherwise, to form the valve-seat of the disk-valve D. This disk-valve is hinged at the end of the post 6, and has an extension, f, at the heel.

sleeved upon the tube 0 and has a limited ver- I tical play thereon.

G are vertical guide-rods, which guide the ferrule F in its vertical play, and coil-springs H are placed around the guide-rods to keep, by their tension, the spider-frame depressed to itslowest position. One of these guide-rods, G, is secured totheferrule and is extended upwardly some distance, and terminates in close proximity to the actuating thumb-piece I of the register J. This register J, which is supported upon the cup 0 by the tube K, which incloses the guide-rod G, may be of any of the known constructions designed to register the number of impulses received from the thumb-piece I, and provided with Visible dials for reading it. To prevent fraudulent tampering with the register, it is inclosed in a case or frame provided with a suitable lock.

L is a stop adj ustably secured to the ferrule F, and projecting with its free end in proper proximity to the heel-extension f of the diskvalve D. This stop L is preferably made slight- 1y yielding at its free end, as} shown in the drawings, wherein Zis a spring-bolt, which has a little vertical play within the stop L, and impinges with its free end'fagainst the heelextension of the disk-valve D.

The parts above described are so arranged that the disk-valve D is kept normally closed upon the mouth of the faucet by the tension of the coil-springs H; but if the'glass to be filled is brought in the proper manner for filling under the faucet and into contact with the conical spider-frame, asufficient upward pressure with the glass will overcome the tension of the coil-springs H, and the displacement of the parts resulting therefrom will open the valve D and impart at the same time the necessary impulse to the register. As soon as the pressure of the glass is relieved, the parts will return to their normal position.

In practice the operator first inserts his glass, as above described, to cause the valve D to open. Then he manipulates the plug of the faucet in the ordinary manner for filling it.

The object of the cup B is to form a guard for the parts located within and protect them also against fraudulent tampering, and the conical form of the spider-cage E is devised to allow the operation of the device with glasses of different diameter. Y

To prevent the device from being removed for fraudulent purposes from the faucet, a seal or lock of any suitable description may be arranged in addition to the set-screws d.

\Vhat we claim as our invention is 1. I11 an attachment for the purpose described, the combination of the following parts: a tube adapted to be slipped over the faucet and having means for securing it thereto, a hinged valve arranged to be seated against the mouth of the faucet, aconically-shaped frame having a vertical play, a suitable tension device arranged to resist the upward play of the conical frame and keep the valve-disks normally closed, a registering device,and an actuating connection thereto operated by the vertical displacement of the conical frame, all arranged and operating substantially as described.

2. In an attachment for the purpose described, the combination of the following parts: an inverted cup or shell, a tube passing centrally through said cup and having means for attaching it to the end of a faucet, a hinged valve below said tube adapted to be seated against the mouth of the faucet, a movable frame having vertical play, a tension device resisting the upward play of the movable frame and keeping the valve-disk normally closed, a registering device, and an actuating connection between the registering device and the movable frame,all arranged and operating substantially as described.

3. In an attachment for the purposes described, the combination of the inverted cup B,the tube 0, having flange c, the hinged valvedisk D, having the heel-extension f, the stop Z, the conical frame or cage E, having ferrule F, the guide-rods G, the coil-springs II, the actuating-rod G, and the register J, all arranged and operating substantially as described.

4. In combination with the register J, having actuating thumbpiece I, the verticallymovable frame E and the actuating-rod G, inelosed within the tube K, all combined and operating as described.

5. In combination with the movable frame E, the coil-spring H, the hinged valve-disk D, having heel-extension f, and the stop L, having spring bolt Z, all arranged and operating substantially as described.
